Today in modern Polymer plants an online quality control is done automatically and alarming the operators immediately so that the operators can react and avoid more damage to the final product. This “close loop”-concept also allows a grading of the pellet lot.

The Film producers, the customers of the Polymer plants, also use web inspection systems to control their final product quality, the quality of the raw materials and also their process parameters.

Between both control concepts exist some interrelationships and also problems, because the environment parameters are different. This relative correlation and the impact for the Polymer and film producers will be discussed with practical examples.
